In the context of soil mapping, what does the term "high intensity map" refer to?

The term "high intensity map" in soil mapping specifically refers to a detailed map that provides comprehensive information about subsurface conditions, including evaluations related to wastewater renovation sites. This type of mapping involves intensive data collection and analysis to capture the necessary geological and hydrological information. It is essential for understanding soil properties, drainage patterns, and potential impacts on groundwater quality, which are crucial for designing effective wastewater management systems.

While the other options represent different types of maps that serve distinct purposes, they do not convey the specialized focus and detail inherent in a high intensity map. For example, a map showing community services provides a broad overview of amenities without the specific, in-depth soil assessments required for wastewater site evaluations. Similarly, a map with extensive historical data may provide context but lacks the current and focused detail on subsurface conditions necessary for evaluating wastewater sites. Finally, a basic outline of a subdivision layout is primarily concerned with physical boundaries and land use, rather than the intricate soil characteristics needed for high intensity mapping.
